`ronn-cLIMsIMa DEvIcn.

To all whom t may concern; 1

Be it hnown that I, WILLIAM S. MORRIS, a citizen of the United States, and resident of St. Louis, Missouri, haveinvented certain new and useful Improvements in Pole Climbing Devices, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, fo-rming a part hereof.

My invention relates to improvements in pole climbing devices, and the objectvof my invention is to construct a removable and portable device AVarranged for detachable connection with a cement or metallic pole.

vVith the above purposes in view my invention consists in certain novel features of construction and arrangement of parts as will `be hereinafter more fully described, pointed out in the claim and illustrated by the accompanying drawings, in which- Figure 1 is a perspective viewof one of my limproved pole climbing devices; Fig. 2 is a sectional plan illustrating my improved device in position in a cementitious pole,

^ cruciform in crosssect-ion; Fig. 3 shows in sectional elevation a fragmentof a cementitious pole, cruciform in cross section, with one lof my improved devices extended through the pole; Fig. 4: is a view similar to Fig. 3, on a reduced scale, showing a modified form of climbing device; and Fig. 5 shows in elevation a pole equipped with my improved climbing device.

` Referring by numerals to the accompanying drawings: 6 designates the body portion of a cementitious pole, and 7 designates wings formed integral with the pole. The body portion, together with the wings, tapers from end to end, and in the formation of the pole I contemplate molding the body and the wings as a monolithic structure. This form of pole will be, in all probability, the style of pole that I will build and place upon the market, hence the climbing device will be designed with special referenceto said pole.

Formed through the body of the'pole, at

an angle relative to the wings, there is a number' of openings such as 8 which extend entirely through the body portion 6 ofthe pole.

The climbing device proper comprises a Specicatonof Letters Patent.V

straight body portion 9 having at its one end a head 10. Extended from and formed integrally with the body portion at its end opposite the head 10 there is a pair of arms 11 which stand at an angle relative to the body portion 9. outer ends of the arms 11 are the vertical arms 12, and connecting the arms 12 and extended integrally from their lower ends is a step or grip 13.

In view of the fact that the cementitious pole precludes the use of ordinary linemens spurs, and in view of the fact that it is objectionable to equip the poles with fixed climbing devices it will be necessary for the linemen to carry a number of these removable devices. These devices are preferably made of a single piece of steel rod, hence it will be no inconvenience for the lineman to carry a number of the devices.

In practical use the body portion 9 of the climbing device is extended through one of the openings in the pole, with its head 10 projected entirely through and engaging Vthe opposite face of the poleso that the device may not be readily withdrawn and, as clearly shown in Fig. 2, when the device is in place in the pole the vertical arms 12 will engage the wings 7 of the pole and prevent the device from` rocking laterally, or the body 9 from rotating in the opening in the pole. I/Vhen such a climbing device is provided with an out-standing step or grip, such as 13, it will be necessary to provide some means for preventing the rotation of the body 9 in the opening in the pole.

If forms of poles other than the form shown are employed, some means equivalent to the vertical arms 12 must be resorted to, hence I do not wish to be understood as limiting myself to the specific construction of this feature of my climbing device.

In Fig. il, I illustrate a modified form of climbingdevice which consists simply of a headed rod projected through an opening in the pole. Inasmuch as this device is a Vremovable and portable climbing device for use in connection with cement or metallic poles, I consider it within the scope O-f myV Formed integral at the and a step portion widened `to engage both and having holes through the line of junoturerof said Wall, the step hai-ving av body portion insertible through the hole and an angular end togengarge one Vend of the hole name to this specification, in presenoeof two subscribing Witnesses.` y
